getCellDataAttributes
public DataAttributes getCellDataAttributes(int row, int column)
Returns the meta-attribute as Java-Object. The object type that is expected by the caller is defined in the TableMetaData property set. It is the responsibility of the implementor to map the native meta-data model into a model suitable for reporting. Be aware that cell-level attributes do not make it into the designtime dataschema, as this dataschema only looks at the structural metadata available and does not contain any data references.- Specified by:
getCellDataAttributes
in interfaceMetaTableModel
- Parameters:
row
- the row of the cell for which the meta-data is queried.column
- the index of the column for which the meta-data is queried.- Returns:
- the meta-data object.
-
isCellDataAttributesSupported
public boolean isCellDataAttributesSupported()
Checks, whether cell-data attributes are supported by this tablemodel implementation.- Specified by:
isCellDataAttributesSupported
in interfaceMetaTableModel
- Returns:
- true, if the model supports cell-level attributes, false otherwise.
-
getColumnAttributes
public DataAttributes getColumnAttributes(int column)
Returns the column-level attributes for the given column.- Specified by:
getColumnAttributes
in interfaceMetaTableModel
- Parameters:
column
- the column.- Returns:
- data-attributes, never null.
-
getTableAttributes
public DataAttributes getTableAttributes()
Returns table-wide attributes. This usually contain hints about the data-source used to query the data as well as hints on the sort-order of the data.- Specified by:
getTableAttributes
in interfaceMetaTableModel
- Returns:
- the table-attributes, never null.
-
getRowCount
public int getRowCount()
Returns the number of rows in the model. AJTable
uses this method to determine how many rows it should display. This method should be quick, as it is called frequently during rendering.- Specified by:
getRowCount
in interfaceTableModel
- Returns:
- the number of rows in the model
- See Also:
getColumnCount()
-
getColumnCount
public int getColumnCount()
Returns the number of columns in the model. AJTable
uses this method to determine how many columns it should create and display by default.- Specified by:
getColumnCount
in interfaceTableModel
- Returns:
- the number of columns in the model
- See Also:
getRowCount()
-
getColumnName
public String getColumnName(int columnIndex)
Returns the name of the column atcolumnIndex
. This is used to initialize the table's column header name. Note: this name does not need to be unique; two columns in a table can have the same name.- Specified by:
getColumnName
in interfaceTableModel
- Parameters:
columnIndex
- the index of the column- Returns:
- the name of the column
-
getColumnClass
public Class getColumnClass(int columnIndex)
Returns the most specific superclass for all the cell values in the column. This is used by theJTable
to set up a default renderer and editor for the column.- Specified by:
getColumnClass
in interfaceTableModel
- Parameters:
columnIndex
- the index of the column- Returns:
- the common ancestor class of the object values in the model.
-
isCellEditable
public boolean isCellEditable(int rowIndex, int columnIndex)
Returns true if the cell atrowIndex
andcolumnIndex
is editable. Otherwise,setValueAt
on the cell will not change the value of that cell.- Specified by:
isCellEditable
in interfaceTableModel
- Parameters:
rowIndex
- the row whose value to be queriedcolumnIndex
- the column whose value to be queried- Returns:
- true if the cell is editable
- See Also:
setValueAt(java.lang.Object, int, int)
-
getValueAt
public Object getValueAt(int rowIndex, int columnIndex)
Returns the value for the cell atcolumnIndex
androwIndex
.- Specified by:
getValueAt
in interfaceTableModel
- Parameters:
rowIndex
- the row whose value is to be queriedcolumnIndex
- the column whose value is to be queried- Returns:
- the value Object at the specified cell
-
setValueAt
public void setValueAt(Object aValue, int rowIndex, int columnIndex)
Sets the value in the cell atcolumnIndex
androwIndex
toaValue
.- Specified by:
setValueAt
in interfaceTableModel
- Parameters:
aValue
- the new valuerowIndex
- the row whose value is to be changedcolumnIndex
- the column whose value is to be changed- See Also:
getValueAt(int, int)
,isCellEditable(int, int)
-
addTableModelListener
public void addTableModelListener(TableModelListener l)
Adds a listener to the list that is notified each time a change to the data model occurs.- Specified by:
addTableModelListener
in interfaceTableModel
- Parameters:
l
- the TableModelListener
-
removeTableModelListener
public void removeTableModelListener(TableModelListener l)
Removes a listener from the list that is notified each time a change to the data model occurs.- Specified by:
removeTableModelListener
in interfaceTableModel
- Parameters:
l
- the TableModelListener
